About L.E.S.S. SA
L.E.S.S. SA is a photonics company founded in 2012 in Renens (Switzerland) that develops and manufactures the patented lighting technology LuxiBright®. LuxiBright® combines a miniaturized laser source with a nano-active optical fiber approximately 1 mm thin: glass nano-antennas integrated into the multi-layer fiber control the direction and angle of the lateral light emission (15° to 80°), while active pigments convert the laser light into the desired color. This eliminates the diffusers, reflectors and large heat sinks of classic LED architectures – according to the manufacturer, the systems are up to 70% lighter, with up to 50% fewer components and up to 40% lower energy consumption. The product portfolio comprises machine vision lighting (LuxiRing Ø 40–420 mm under 9 mm installation depth, LuxiLine 300/600/900 mm), inspection lights for pharmaceuticals, micromechanics and watchmaking (MIRA2, PRISMA, VisiBright, VisiDark), and functional vehicle lighting including concept and series production projects. Three platforms are offered for automotive: Discovery (from 1 piece), Performance (from 10 pieces, IP67) and Road (from 1,000 pieces).
